AI Technical Summary
When the load load of existing cart rubber wheels is unbalanced, the shock absorption effect is poor, and the damping force is insufficient, resulting in the inability to effectively buffer, which affects the user experience.
Using a tire design including a rubber outer layer and an inner layer of the foam ring, combined with multiple spring damping elements and limiting grooves, the first and second spring damping combination ensures good shock absorption under different loading conditions. The effect is improved by the anti-slip texture of the rubber outer layer and the foam rubber material.
It achieves good shock absorption effect under different load-bearing conditions, improves the comfort and wear resistance of the cart, and ensures stability and safety in various scenarios.

Abstract
Description
Technical Field
[0001] The present application relates to the field of tires, and in particular to a wear-resistant cart rubber wheel. Background Art
[0002] A trolley is a transport vehicle that is pushed and pulled by manpower. Although the material handling technology of a trolley is constantly developing, a trolley is still used as an indispensable transport tool. The trolley is widely used in production and life because it is low in cost, simple in maintenance, easy to operate, and light in weight. It can work in places where motor vehicles are inconvenient to use, and is very convenient for transporting lighter items over a short distance. Existing trolley wheels are usually made of hollow rubber material, and the cushioning properties of the rubber material itself are utilized while spring damping is added for shock absorption. If the damping force used is small and the trolley is overloaded, the damping reaches the limit position and the shock absorption effect cannot be achieved. If the damping force used is large and the trolley is underloaded, the elastic element of the spring damping cannot be effective, which also leads to a poor shock absorption effect.
[0003] The structure of the product can refer to the solid tire for a trolley disclosed in the Chinese patent document announcement number: CN213705080U, which includes a tire outer ring, a tire carcass and a tire inner ring, and the tire outer ring, the tire carcass and the tire inner ring are bonded by vulcanization; the surface of the tire outer ring is provided with anti-skid patterns, and the anti-skid patterns include mutually communicating transverse patterns and diagonal patterns, and the diagonal patterns are located on both sides of the transverse patterns and are symmetrical to each other; tire holes are provided in the tire body and pass through both sides of the tire body, and rubber strips are provided through the tire holes, and the cross-section of the rubber strips is a cross shape along the radial and tangential directions of the tire body.
[0004] In the above structure, shock absorption is only performed through the inner ring of the tire, resulting in a poor shock absorption effect.
[0005] Therefore, a wear-resistant cart rubber wheel with good shock-absorbing effect is needed. Utility Model Content

[0030] Reference Figure 1-4 The wear-resistant cart rubber wheel comprises: a wheel hub 100, a tire 101, a mounting tube 107, a mounting frame 103, and a mounting assembly 104. The tire 101 comprises a rubber outer layer 105 and a foam ring inner layer 106. A mounting plate 108 for mounting to a cart is fixedly connected to the mounting tube 107, and a mounting hole 109 is provided on the mounting plate 108 for convenient installation on the cart. A mounting column 110 with one end extending into the mounting tube 102 is fixedly provided on the mounting frame 103. A buffer plate 111 is slidably connected in the mounting tube 107, and the buffer plate 111 is fixedly provided at one end of the mounting column 110. A connecting plate 112 is slidably provided in the mounting tube 107, and a first spring damper 113 is provided between the connecting plate 112 and the buffer plate 111. The first spring damper 113 is used to reduce shock and buffer the cart when the cart is lightly loaded. The second spring damper 114 is fixedly connected in the mounting tube 102, the connecting plate 112 is provided with an opening 115 for the second spring damper 114 to pass through, and the buffer plate 111 is provided with a limiting groove 117 for limiting the second spring damper 114. With one end of the second spring damper 114 abutting against the buffer plate 111, when the cart is heavily loaded, the first spring damper 113 and the second spring damper 114 cooperate to buffer the cart.
[0031] A screw rod 118 passing through the mounting tube 107 is rotatably connected inside the mounting tube 107, and the screw rod 118 passes through the connecting plate 112 and is threadedly connected to the connecting plate 112. By rotating the screw rod 118, the connecting plate 112 is driven to move, so that one end of the second spring damper 114 abuts against the buffer plate 111 and is positioned in the limiting groove 117, so that the second spring damper 114 cooperates with the first spring damper 113 to reduce shock.
[0032] The mounting frame 103 includes a connecting portion 119 fixedly connected to the mounting column 110 and a housing 120 for mounting the wheel hub 100. A buffer groove 121 is provided in the housing 120. A sliding block 122 is slidably connected in the buffer groove 121. A bearing 123 for mounting the wheel hub 100 is rotatably connected to the sliding block 122. A damping pad 124 is provided in the buffer groove 121 for buffering the sliding block 122. When the cart passes through a pothole road, the tire is buffered to a certain extent to avoid damage to the wheel hub 100. Anti-skid patterns 125 are distributed circumferentially on the rubber outer layer 105.
[0033] The inner side of the rubber outer layer 105 is provided with a circumferentially arranged limit strip 126, and the outer side of the foam ring inner layer 106 is provided with a groove for the limit strip 126 to be embedded. This prevents the foam ring inner layer 106 from shifting inside the rubber outer layer 105. The rubber outer layer 105 is made of butyl rubber and has good wear resistance. The rubber outer layer 105 is circumferentially distributed with anti-skid patterns, and the foam ring inner layer 106 is made of foam rubber, which can play a shock-absorbing role and has good comfort.
